Ceiling boards

ABSTRACT

Ceiling boards are made of pressed cardboard, wood or other suitable material and have an outer surface coated with colored flakes carried by polyurethane. This outer surface may be rough or provided with a smooth finish. The boards may be square or of the so-called 3D type provided with projecting edges.

CEILING BOARDS This invention relates to ceiling boards.

An object of the present invention is the provision of ceiling boards for all types of houses and homes which is most effective in appearance and which will provide pleasing and unusual luminous effects.

Other objects of the present invention will become apparent in the course of the following specification.

in the accomplishment of the objectives of the present invention it was found desirable to provide a board made of Masonite, wood, cardboard, pressed cardboard or any other suitable material. The board is preferably somewhat soft and light, although heavy and hard boards may be also used. The outer surface of the board which will he the visible part of the ceiling is covered by colored plastic flakes carried by a coating of polyurethane. Flakes of any desired colors may be used to form mixtures of any desired color combinations, although preferably some of the flakes should be bright and light reflectant.

In use, the liquid polyurethane is sprayed or brushed on the board, then, while the liquid is still wet, the colored flakes are sprinkled over the liquid and allowed to dry. The outer surface may remain rough. However, it is preferable to apply a smooth finish to the outer surface which requires at least three finished coats.

The boards may be plain square boards. However, preferably so-called 30 boards are used which are provided with supporting strips projecting to the extent of about onehalfinch beyond the four sides of the board.

The invention will appear more clearly from the following detailed description when taken in connection with the accompanying drawing, showing, by way of example only, a preferred embodiment ofthe inventive idea.

In the drawing:

FIG. 1 is a perspective view ofa ceiling board of the present invention; 1

FIG. 2 is a section along the line 11-11 of H0. 1;

FIG. 3 is a partial rear view of the board.

The ceiling board shown in the drawing includes a basic board 10 which can be made of Masonite, wood, cardboard, pressed board or other suitable material; it may be heavy and hard or soft and light. The drawing shows a square board which may have the usual size of 2 feet by 2 feet, although, obviously, boards of other sizes can be used.

In accordance with the present invention, colored flakes 11 consisting of plastic strips are mixed with polyurethane liquid. This liquid is applied over the outer surface and the edges 12 of the board 10 and is allowed to solidify to form a coating 13. The flakes 13 may be of any suitable colors, such as brown, gold, white, red, orange, etc. and can be mixed in any desired combinations. To provide a shiny ceiling, a preponderance of bright, light-reflecting flakes should be used.

After the coating has dried, it may be allowed to remain as it is, thereby providing a rough outer surface. However, it is preferable to polish it to provide a smooth surface. At least three finished coats may be necessary to provide a perfectly smooth finish.

As already stated, the board 10 can be used by itself, a plurality of such boards being applied to the ceiling in the usual manner. However, a preferred construction shown in the drawing is that known as 3D, wherein the underside 14 of the board is provided with strips 15 made of the same material as the board and fixed thereto by glue, cement, nails or in any other suitable manner. The strips 15 constitute a firm support for the board and they extend beyond all edges of the board to the extent of about one-halfinch.

When several such boards are applied to a ceiling, they will form a most effective square pattern. The shining flakes will create a most pleasing and unusual luminous effect.

I claim:

1. A ceiling board, comprising in combination, a board having an outer flat surface, an inner surface and edges enclosing said surfaces, a coating of polyurethane upon said outer surface and said edges, a plurality of multicolored flakes carried by said coating and extending outwardly from said outer surface and said edges and strips attached to said inner surface, said strips extending parallel to and beyond said edges.
